Construction law firm Cohen Seglias Pallas Greenhall & Furman is spreading its geographic wings once again, as it announced plans to enter the Washington, D.C. market by acquiring four-lawyer Thaler Liebeler.

The key to the deal, which is set to close on June 29, is partner Paul S. Thaler, who will become managing partner of the new Washington location.

His practice is geared toward representing scientists and institutions who have received grants that are accused of scientific and research misconduct.

That practice will be merged with that of Harrisburg-based partner Christopher Carusone, chair of the Cohen Seglias’ government law and regulatory affairs group and former secretary of legislative affairs for former Pennsylvania Gov. Tom Corbett. Carusone, who returned to private practice in 2013, joined Cohen Seglias last year after a short stint with Conrad O’Brien. He focuses on workplace and Title IX investigations.

“We think Paul’s practice dovetails nicely with Chris’ practice,” said Edward Seglias vice president and shareholder of Cohen Seglias. “But we also liked the idea of entering the Washington market.”
